      • Linux Handbook9 Best Free Website Downtime Monitoring Services [Ed: One can set up one's own instead of outsourcing]

        It is crucial to monitor the availability of your website if you do not want your readers/customers to go away.

        Whether it is an online business or a blog, website downtime can hurt your website's online presence.

        It is also helpful to know if you picked the right server for your website if you are aware of the downtime. If your server is down for a long time at regular intervals, you need to identify what’s wrong with the server (or the configuration).

        Honestly, it is not always a malicious actor or an issue with a technology that you use; sometimes, it's just the server that's at fault.

      • OMG UbuntuCurtail is an Awesome Image Compressor Tool for Linux - OMG! Ubuntu!

        Running a blog like this means I need to keep one eye on the size of screenshots I use in posts — the smaller the images I upload the faster the page loads for you.

        Thus having access to a good image compressor tool is a must.

        Thankfully for those of us being mindful of bandwidth we are spoilt for choice. Not only is there a broad range of image compression apps for Linux, from powerful CLI type through to noob-proof GUI ones, there’s also a veritable surfeit of online compressors (including superbly useful Squoosh, which can work offline).

        Thing is, I prefer desktop apps where possible.

      • FOSSLinuxHow to start GNOME desktop from command line in Debian | FOSS Linux

        GNOME, an acronym for the GNU Network Object Model Environment, is a graphical user interface and set of computer desktop apps for Linux OS users. It is aimed at making Linux OS an easy-to-use OS for non-programmers. With GNOME, you can set the interface to look like Windows or macOS. GNOME is a free and non-proprietary desktop environment for all the major Linux distros, including Fedora Linux, Debian, Ubuntu, Enterprise Linux, Red Hat, SUSE, and others.

        On the other hand, a command-line alias cmd, CLI, prompt, console, or terminal refers to a text-based user interface (UI) utilized in viewing, manipulating, handling, running programs, and managing comp files as interacting with the computer. It is much like Windows Explorer or Finder on the macOS but without the graphical interface.

        GNOME has emerged as the most efficient, reliable, and stable of all the available desktop environments for Linux while retaining its user-friendliness features. GNOME began as a free and open desktop alternative to proprietary options like KDE at the time, and it has been going strong ever since.

      • Linux Shell TipsWhat’s the Difference Between Grep, Sed, and Awk Commands

        We cannot confidently call ourselves Linux file management experts without the mastery of text processing. Three known command-line tools (grep, sed, and awk) have built their reputation as Linux text processors. They come pre-installed on all major Linux operating system distributions hence no need to query their existence via a Linux package manager.

        Despite grep, sed, and awk commands being uniquely attributed in their text processing functionalities, some simple scenarios force their functionalities to slightly overlap.

        For instance, all these three commands can comfortably query the possibility of a file pattern match and forward the query results to standard output.

      • ArduinoMove this custom robotic arm through a touchscreen interface | Arduino Blog

        Normally, robotic arms are controlled by a GUI running on a host PC, or with some kind of analog system that maps human inputs to various degrees of rotation. However, Instructables user Maurizio Miscio was able to build a custom robotic arm that is completely self-contained — thanks to companion mobile app that resides on an old smartphone housed inside a control box.

        Miscio started his project by making 3D models of each piece, most of which were 3D-printed. These included the gripper, various joints that each give a single axis of rotation, and a large circular base that acts as a stable platform on which the arm can spin. He then set to work attaching five servo motors onto each rotational axis, along with a single SG90 micro servo motor for the gripper. These motors were connected to an Arduino Uno that also had an HC-05 Bluetooth€® serial module for external communication.

      Consider what would happen if you were using one of the software applications that you have purchased by paying a hefty amount to the company and which you have been using for a decade without any issues.

      Although you know, this was the only application that could do specific work, and there was no alternative option to this application available on the market. Therefore, you couldn’t even imagine your life without that software.

      But unfortunately, one day, the company announced that we will not provide further updates or support to this particular application because they are shutting down their company due to some internal conflict. You will be under immense stress after hearing the announcement and finding a way out of this situation but you can’t do that because you don’t have the necessary resources to update an application.

      Now you are stuck in the middle of nowhere.

          Some models of Oppo and OnePlus mobile phones will not be sold in Germany following a ruling by a Mannheim court in favour of Finnish telecommunications equipment vendor Nokia over a patent.

          The ruling, by a regional court in the southwestern German city, was the second in as many months and said Oppo's use of some 5G and 4G technologies infringed Nokia's patents, according to a report in the South China Morning Post, which cited a statement from the Finnish firm.

          The first ruling was issued in June. Oppo and OnePlus are both owned by Chinese firm B.B.K. Electronics which also owns the vivo, realme and iQoo brands.

          Oppo constantly ranks as the fourth selling smartphone brand after Apple, Samsung and Xiaomi. Neither Nokia nor Oppo's owners have issued a public statement about the case.

          I run a BBS (Bulletin Board System) on the Mystic BBS software which I find fun because it brings back memories of connecting to BBS when I was much younger before the Internet was popular.

          It is nostalgic to see the chuncky text and ansi graphics when I connect using a client like Netrunner or Syncterm however most of the time, I am not interested in the nostalgia but just to connect quickly to check for messages or any new activity.

          Since discovering gemini, this has stolen some of the time that I previously would have spent working on the BBS or chatting there or other improvements.

        • Re: Thoughts on RSS

          Even the negatives on his list seem like huge positives.

          Technically, he’s wrong here; there’s nothing stopping an RSS feed from getting slathered in JavaScript and CSS and there are many reading apps that will display that.

          But culturally, that practice isn’t very widespread, thankfully, and RSS (including Atom) has been a readers’ bastion similar to what we have here on Gemini. This is a good thing, not a bad.

          I’ve always seen Gemini as kind of similar to RSS; another way to publish your stuff, that’s more reader-friendly. Friendlier to mashups, ebook exports, tours, offline, your own styling, your own font choices, a clean and consistent typography that goes across sites, not just your own.


* Gemini (Primer) links can be opened using Gemini software. It's like the World Wide Web but a lot lighter.
